Manganese & Zinc Phosphate Coating | Metal Coatings

In other instances, phosphate coatings are applied to threaded parts and top coated with oil (P&O) to add anti-galling and rust inhibiting characteristics. The phosphating process relies on the basic pickling reaction that occurs on the metal substrate when the process solution comes in contact with the metal.

Pretreatment for Painting | Products Finishing

Feb 18, 2011 · Zirconium is not regulated as a hazardous metal in North America or Europe. The new coating can be applied in fewer total stages than a zinc phosphate process and fewer chemical stages than both zinc and iron phosphate. In its simplest form, the process consists of five stages—two chemical stages and three water-rinse stages.
